David Reiss commented on THRIFT-110:
------------------------------------
I don't think you should worry about optimizing for negative field ids. Their
use is discouraged. (Negative data is different, of course.)
I think the only reasonable variable-length encoding for floats would be to
switch between a single and double precision format.
I think one big issue that needs to be resolved with regards to encoding extra
information in type identifiers is how to deal with the case of containers
which only use one type identifier for the entire container.

> Thrift is not very compact in writing out data as (say protobuf) . It does
> not have the concept of variable length integers and various other
> optimizations possible . In Solr we use a lot of such optimizations to make a
> very compact payload. Thrift has a lot common with that format.
> It is all done in a single class
> http://svn.apache.org/viewvc/lucene/solr/trunk/src/java/org/apache/solr/common/util/NamedListCodec.java?revision=685640&view=markup
> The other optimizations include writing type/value in same byte, very fast
> writes of Strings, externalizable strings etc
> We could use a thrift format for non-java clients and I would like to see it
> as compact as the current java version
